WILLIAM C. I-IIIEIRINGl OF NEWARK, NEW JERSEY, ASSIGNOR-TO J. E. MERGOTT CO., OF NEWARK, NEW JERSEY, A CORPORATION OF DELAWARE.

KNOB FOR BAG FASTENERS, ETC.

Application filed July 28, 1926. Serial No. 125,378.

This invention relates to ornamental knobs, particularly such as are covered with leather, flexible fabric or like material and has special reference to that type of knobs used in connection with bag fasteners, the same being van improvement over my earlier patent on bag fastener, ho. 1,181,151, tilted May es, 191e. i

rlhe present invention has as one of its features the provision of a light but strong spherical knob either plain or covered conipletely, with any flexible sheet material, except for a single narrow circui'nferential metallic band acting as an ornamental reenforcement and also to eifectively secure the cover material overthe sphere.

lt is another object to devise a covered ball knob susceptible of easy .and economical manufacture and assembly.

Other advantages will become apparent in the following detailed description and will appear in the accompanying drawing, forming an important part of this disclosure, and in whchz Figure 1 is a perspective view of an embodiment of bag casing.

Figure 2 is a sectional viewrtaken on line 22 of Figure 1, drawn to an 'enlarged scale.

Figure 3 is a similar sectional view showing the parts in a separated but related position.

Figure et is a perspective View of a bag or like connecting ele-ment in detail.

Although the knob is shown .as used in connection with a bag frame, it is to be understood that the novelty of the invention resides in the knob structure per se,

lthe same being applicable to many other uses, such for instance as drawer pulls, curtain pole ornaments .and like purposes. t

In Figures 1 and 2 a conventional pair of channelled bag frames are designated by the numerals 10 and 11 respectively, the same being hingedly engaged at the ends of the angularly bent members in the usual manner.

One of the frame members, as 11, has in its upper surface an opening 12 to receive a looped extension 13 formed'on a substantially circular plate 111, containing an opening 15 and securedV by solder to the bottom of inverted. cup 1G, the annular flange the invention as applied to aV of which also receives a lip 17 on the other loop member.

A space 18 in the loopis suited to receive the flattened outer portion 19 of a spring of the usual type anchored between the flanges of the channel 11, the function of such spring being to press the flange edges oVF the cup into Contact with the upper surface of the frame member 10, the cup being disposed symmetrically over both frame members.

A triangular catch 2() is rigidly fitted on the frame member 10, opposite the opening 12, its inclined upper surface engaging the edge of the cup when closing the frame members, raising the free edge of the cup until it has passed the high pont of the catch, and then snap to engage the vertical edge of the catch under the effect of the spring 19. Y

On the bottom 21 of the inverted cupl 16 opposite its flanged edge, 1s a hub 22 containing a screw threaded opening, register- 23 and 23', hemispherical or nearly so,

pressed fromsheet metal and containing axial openings 24 and 24, their bases' being level.

Rigidly secured in the opening 241 is a fixed cylindrical blind nut having a thin convex head 26 and set permanently in the nut is one end `of a screw threaded rod 2?.

The hub 22 of the inverted attaching cup is inserted through the opening 2e" and the rod 27 is engaged by the screw threads therein, providing means to draw rthe shells 23 and 23 towards each other.

Disposed circumjacent the base edgesl of the shells is a band 28 curved transversely on its outer surface and formed on its inner surface is a thin annular flange 29 disposed lbetween the base edges, or this flange may be increased to constitute a disc having a central opening through which the rod 27 can freely pass.

y The effect of the band which is highly finished, to materially reeuforce sti tl il les en the knob structure, sphericzl eleinents and obscuring the joint therebetween, and, as these eleinents are drawn irinly together by the bolt and nut device, a rigid, nnyielding but light knob is produced.

As it is customary to envelop the trames of a bag in a thin leather or tabl-ie easing, in harniony with the bag material, it is also desirable to cover the knob with similar inaterial.

The described structure affords a partienlarly easy and secure Ineans tor attaching such co\f*ering, which consists ot thin leather or t'abrie elements 30 and 30 shaped to produce concave-convex casings held at the ends of the ltnob by being clamped by the elements 2l and 26 respectireand at the center b y the band 28; the edges ot' the casgiuding the hennings lnay be carried inwardly as at 8l, it

preferred and thus positively.' clamped between the base edges ot the hen'iispherical eleinents and the flange or disc creating an etticient holding ineans.

From the foregoing it will be seen that a novel, practical and alnablo spherical knob structure has been disclosed in its preterred torni, but it will b-e recognized that ininor inoditications may be resorted to within the spirit of the invention as being covered by the scope otl the appended elairns.

Hat/ing thus deicribed iny invention, what l claiin as new and desire to secure by ietters Patent, is

l. A hollow spherical knob coinpritfzing two heinispherical eleinents each having axial openings, a nut fixed in one opening to extend inwardly, a threaded rod in said nut, and a second nut revoluble in the opening ot the other eleinent to engage. said rod whereby said elements may be drawn towards each other.

2. A hollow spherical knob comprising two equal heinispherieal shells haring axial openings, a bolt having' a thin convex head tixed in the opening or one shell, a nut revoluble in the opening of the other shell to engage said bolt, and means to guide the base edges of said shells, said means obscuring the joint therebetween.

3. A hollow spherical knob comprising two equal heinispherical shells having axial openings, a bolt fixed in one shell, a nut rotatable in the other shell to engage said bolt, a band circninjaeent the base edges of said shells, and an inreaching central tlange en said band disposed between the base edges.

it. A hollow spherical knob comprising two equal heinispherical shells hayi g axial openings, a bolt having a thin convex head. said bolt passing through an opening in oneI ot said shells, a nut engageable with said bolt and passing through the opening in the other shell, said nut having an enlswc head, a band over the edges ot said shell Said band' having an inreaching nie/nicer disposed between the ineeting edges ot the shells, and covering disposed over the surfaces ol said shells, said covering being claniped by the heads of said bolt and nut respectively and held to the shells by said band.

5. A .hollow spherical knob comprising a pair oit shells, a bolt passing axially therethrough, a nut engaging said bolt, a dise disposed between the edges ot said shells a band on said dise cireurnjacent the ed@ and covering material enclosing said shells, said material being clamped between the edges of the shells and said dise, and by the head of said bolt and nut to each shell respectively.

This specification signed this twentieth day of July, 1926.
